ANF thanks the Ministry of Education, Culture, Sports, Science and Technology of Japan (MEXT) for financial support during the doctoral program. We thank Prof. Dr. Yoshitaka Takano (Laboratory of Plant Pathology, Graduate School of Agriculture, Kyoto University, Kyoto, Japan) for providing Colletotrichum tropicale. The cepr1-1 (psi_00082), cepr2-1 (psi00083) and cepr1-1 cepr2-1 (psi_00084) mutants was provided by the RIKEN BRC through the National Bio-Resource Project of the MEXT, Japan. This research was supported in part by the Grants-in-Aid for Scientific Research (21K05597) from the Japan Society for Promotion of Science (JSPS).

N2 - CEP peptide was synthesized and tested for induction of disease susceptibility using Arabidopsis Col-0. When Colletotrichum tropicale was used as a non-adapted fungal pathogen, the conidia germinated to form hyphal-like structures, which successfully penetrated epidermis, eventually causing disease symptoms. In such case, PEN2-, but not PEN3-dependent resistance was likely suppressed by CEP peptide. Similarly, the CEP peptide-mediated disease susceptibility was also effective to a non-adapted bacterial pathogen. Notably, such induced susceptibility was also evident on Arabidopsis mutants lacking the previously identified receptors, suggesting that the CEP peptide modulates Arabidopsis immunity through an unidentified receptor(s).
